Nimbus Defense is an action-puzzle game set in the mysterious skies over New Jersey. Professor BellBottom was in the process of conducting his seemingly harmless experiments when his arch rival, the wicked Professor Peppers, decided that it was his time to shine. On a whim, he decided that if he couldn't create the next big thing in cloud technology, then no one can! Defend Professor BellBottom from the evil Professor's evil inventions of malicious intent using Professor BellBottom's latest invention, physical clouds. Don't ask how they work, because he isn't quite sure either.
